AudioEffectDelay

Inherits: AudioEffect < Resource < RefCounted < Object

Adds a delay audio effect to an audio bus. Plays input signal back after a period of time.

Two tap delay and feedback options.

Description

Plays input signal back after a period of time. The delayed signal may be played back multiple times to create the sound of a repeating, decaying echo. Delay effects range from a subtle echo effect to a pronounced blending of previous sounds with new sounds.

Property Descriptions

float dry = 1.0

Output percent of original sound. At 0, only delayed sounds are output. Value can range from 0 to 1.


bool feedback_active = false

  • void set_feedback_active ( bool value )

  • bool is_feedback_active ( )

If true, feedback is enabled.


float feedback_delay_ms = 340.0

  • void set_feedback_delay_ms ( float value )

  • float get_feedback_delay_ms ( )

Feedback delay time in milliseconds.


float feedback_level_db = -6.0

  • void set_feedback_level_db ( float value )

  • float get_feedback_level_db ( )

Sound level for tap1.


float feedback_lowpass = 16000.0

  • void set_feedback_lowpass ( float value )

  • float get_feedback_lowpass ( )

Low-pass filter for feedback, in Hz. Frequencies below this value are filtered out of the source signal.


bool tap1_active = true

  • void set_tap1_active ( bool value )

  • bool is_tap1_active ( )

If true, tap1 will be enabled.


float tap1_delay_ms = 250.0

  • void set_tap1_delay_ms ( float value )

  • float get_tap1_delay_ms ( )

tap1 delay time in milliseconds.


float tap1_level_db = -6.0

  • void set_tap1_level_db ( float value )

  • float get_tap1_level_db ( )

Sound level for tap1.


float tap1_pan = 0.2

  • void set_tap1_pan ( float value )

  • float get_tap1_pan ( )

Pan position for tap1. Value can range from -1 (fully left) to 1 (fully right).


bool tap2_active = true

  • void set_tap2_active ( bool value )

  • bool is_tap2_active ( )

If true, tap2 will be enabled.


float tap2_delay_ms = 500.0

  • void set_tap2_delay_ms ( float value )

  • float get_tap2_delay_ms ( )

Tap2 delay time in milliseconds.


float tap2_level_db = -12.0

  • void set_tap2_level_db ( float value )

  • float get_tap2_level_db ( )

Sound level for tap2.


float tap2_pan = -0.4

  • void set_tap2_pan ( float value )

  • float get_tap2_pan ( )

Pan position for tap2. Value can range from -1 (fully left) to 1 (fully right).
